Finally a clear relationship between the gut microbiome and Parkinson's disease (PD) has been pubished in Cell. In the article entitled "Gut Microbiota Regulate Motor Deficits and Neuroinflammation in a Model of Parkinson’s Disease" Sampson et al. publish that gut microbes are required for the neuroinflammatory responses motor deficits in a model of Parkinson’s disease in mice.

Newly the conection between gut microbiome and brain has been confirmed and the long time ago searched involvement of gut microbiome in Parkinson's disease pathophysiology has been confirmed with the findings of this work.
